Patented Feb. 16, 19392 UNETED STATES MAR-TIN KATZ, OF BROOKLYN, 'NEW YORK GLASS MOUNTING FOB WINDOWS Application filed. August 5, 1930. Serial No. 473,220.

The present invention relates to improvements in glass mountings for display w1ndows in store front construction, and more particularly to the class that includes a fixed rear sash member, and a detachable front molding or clamp member adapted to removably secure the glass to the rear member.

The objects include means for qulckly assembling, adjusting and removingthe front clamp member to suit glass of variable thickness. Also to provide screw-actuated locking means adapted to be adjusted without dis placement of its parts to conveniently receive and separately engage the front clamp memher along its length and-lock the glass in'position; And also to provide a construction in which the weight of material used is much reduced by its disposition in accordance with the stresses thereon. V

For further comprehension of the invention, and of the objects and advantages thereof, reference is had to thefollowing description and accompanying drawings and to the appended claims in which the various features of the invention are more particularly set forth.

Referring'to the drawings in which similar characters of reference designate like parts throughout the several views:

Figures 16 and 2b are respectively modificatory views corresponding with Figs. 1 and 2. V

Figure 3b is a view in side elevation taken at right angles to. Fig. 2b.-

Referring to Figs. 1, 2 and 3 of the drawings, numeral 1 designates a fixed frame or sill section having in part a metal facing consisting of a front portion 2 rearwardly folded to form a bottom or base wall 3 provided with a rear flange 3a, and upon the base wall is mounted a socket section 10 folded lengthwise to form an offset back wall 5 of a fixed rear sash member generally indicated at 4. The back wall 5 bears against the rear. flange 3a and the upright portion of the sill l, and from which latter point it is forwardly folded parallel to and in spaced relation with the base wall 3 to form a trough 6 extending the fulllength of the sash member and provided with a forward upright flange 7 adapted to form a seat that engages for support the rear marginalface of the glass 8, the bottom wall of the trough having perforations pressed therethrough and threaded to engage screws 9 arranged at intervals along the length of the trough.

The socket section 10, back wall 5 and trough 6 comprise a hollow base for the rear sashmember a, and along the front side edge of the socket section an offset stop ledge 13 is 'formed that provides a lengthwise space with respect to the base wall 3. Apertures having open sections 14 and 20 provided with upturned marginal flanges 12 are formed through the socket section 10, the flanges being adapted to lead collected drain water to convenient points of escape, not shown, and 80.

on opposite sides of the sections 14 the free edges of the flanges are slightly inturned at 15 to form pivot retaining sockets adapted to hingedly receive the pivot ends 16 0f the clamp levers 17, the latter being provided" with arms 18 and 19 projecting oppositely from the pivot line. The side aperture sections 20 provide passages by means of which the pivot ends of the clamp levers may readily be introduced'or removed from the retaining sockets, and to secure the pivots against lengthwise displacement therein the opposite flanges thereof are depressed to loosely engage said ends, and to secure the socket section to the fixed frame, screws 11 are provided. For positioning the glass, the marginal edges thereof are loosely held by conventional blocks, not shown, that bear against the socket sections 10 between the apertures thereof.

The front molding or clamp member 21 is provided along its base edge with an inwardly extending flange 22 adapted to loosely e2:- tend into the lengthwise space formed by the bottom wall 3 and the offset stop member 13, the latter serving to hold the front member against displacement from the bottom wall, and along its opposite edge the member 21 is provided with a bearing flange 23 disposed to engage as a detachable support the front marginal edge of the glass 3 in opposition to the rear seat 7 of the fixed sash member i. Clamping pressure is exerted along the bearing flange 23 by the suitably bent front arms 18 of the clamp levers 17, the said pressure being transmitted through the inner lever arms 19 from the screws 9 alined therewith, and to provide constant engagement between the screw points and lever arms the latter are engaged by the free ends of springs 24, fixed at their opposite ends to the socket plate 10.

As thus provided with springs the clamp levers are under control of the screws in their opposite movements, any loss motion in the screw threads being taken up by the springs of the separate levers, thus serving to maintain the latter either in an open position for inserting or removing the glass, or in a closed position for locking the same between the opposite sash members.

Referring to the modification shown in Figs. 1a,,2a and 3a of the drawings, the frame or sill 29, having a rear section 30, is provided with a relatively thin metal facing 31 extending over its front face and folded rearwardly to form a bottom wall 32, the latter being provided with narrow rear flange 33 braced against the rear section 30 of the frame. Upon the bottom facing wall 32 is mounted a fixed rear sash member composed of relatively thin metal shaped to provide a base section 3%, having along its rear side edge a right angle offset fold to form a back Wall 35 that bears against the flange 33 anl the frame section 30. From the back wall the metal of the sash member is forwardly folded parallel to and in spaced relation with the base section 34 to form a trough 36 e::- tending the full length of the sash member and provided with a forward upright flange 37 adapted to form a seat that engages for support the rear marginal face of the glass 33, the bottom wall of the trough having perforations pressed therethrough and threaded to engage screws 39 arranged at intervals along the length of the trough. The base sec tion 34 and the back wall 35 together with the trough 36 comprise hollow base for the rear sash member, the base section being shaped along its front marginal edge to form an offset stop ledge l0 that provides a lengthwise space with respect to the bottom wall Within the hollow base of the rear sash member and conforming with the inner faces of the walls thereof, are a plurality of lever frames 41 of relatively thick metal spaced apart from one another to stifien the respective walls and to form a support for the marginal edge 42 of the glass 38 and to provide a pivotal socket 433 for hingedly mount ingthe clamp levers 44:. At their front ends the lever frames 41 are ofiset at 45 to correspond in shape and to support the thrusts against the stop ledge 40 of tee base section 34, and for securing the lever frames in position within the rear sash member screws 46 are used as shown extending through the base of said frames and into the sill 29-.

The front clamp or sash member 47, the clamp levers l4 and the screws 39 (shown in 2a) correspond in construction and operation to the similar parts shown and described for Fig. 2.

Referring to the modification shown in Figs. 1Z 2?) and 3b of the drawings, the frame l9, having the rear section 50, is also provided with a relatively thin metal facing 51 extending over its front face and folded rearwardly to form a base wall 52, and upon the latter is mounted a lever frame 53 having a construction similar to that shown at ll in 2a and adapted essentially for engagement with a marginal edge 54 of the glass 55, and for providing pivotal socket-s 56 for the lever arms 57 and for stop ledges 58 that engage the base flange of the clamp or front sash member 59. As shown in Fig. 1b the rear section 50 of the frame l9 is provided with a front face 60 constituting a bearing seat for the inner marginal surface of the glass 55, and extending through the face 60 into the section 50 are recesses 61 adapted to receive the rear ends of the lever frames 53, the latter being positioned therein with respect to the clamping action of the front sash member 59 and clamp lever 57 upon the glass, screws 61 being provided to hold the lever frames 53 in position upon the main frame 49.

In the latter modification a pair of upper horizontal sash members are shown employing a limited number of metal parts andlsubstitnting for the metal rear sash member a face of the main wood frame, the remaining metal parts including the front sash member, lever frames and clamp lever being constructed and operated in the manner described for the modification shown in Figs. 1a, 2a and 3a.
